Which of the following is the equation of a line perpendicular to the line y=-3/2x+4 passing through the points (3,9)

Y-y1=m(x-x1) 

Y-9 =2/3 (x-3) 

Y-9=(2/3)x - 2 

Y=(2/3)x + 7 

Heres some formulas...

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
